Similar story here but t'other way round: my usual cycling partner started with cardiac rhythm problems around 5 years ago, which resulted in him getting an eBike and riding at battery-conservation speed while I was champing at the bit to be away ahead. Then we'd come to a hill and he'd cruise up it while I slaved away with my heart on 110% theoretical max trying not to fall too far behind. Eventually we ended up cycling separately, partly because of this but also because my legs lasted a lot longer than his battery.bikes4two wrote: ↑22 Mar 2023, 11:15pm My cycle touring friend of many a long tour, came with me last year on a hilly ride around the south downs - me on my e-bike, him on an un-asisted machine. The poor chap was absolutely knackered and whilst I congratulated him on his efforts I pointed out that he really needed to consider if such exertion was in fact good for him at his stage of life (something his other cycling buddies had mentioned too.).
Then last year I knuckled under to anno domini and put a motor on my bike. It didn't even things up, though, because in the meantime his heart hasn't got any better and his weight has soared, so that even with the motor he can only manage 18-19 kph. Last outing I did on my own I averaged 23.7 kph, so when we ride together I'm still champing at the bit.
